Wondering if i should set my 2600k to 5ghz

trisp · 19 Jun 2011 at 01:34

I originally just went for 4.4ghz and managed to get that stable @ 1.32 volts and has been stable since then, the other day i decided to have a mess around updated my bios and cleaned out my pc and then proceeded too see what i could get and it seems that my chip is not all that great of an overclocking chip compared to some...

4.4ghz @ 1.31
4.6ghz @ 1.38
4.8ghz @ 1.45
5ghz @ 1.51 (im still under the recommend magic 1.52 intel number

)

Now the first two are okay overclocks and it should not be a problem running them at all, my question is would the other two be okay for 24/7 use and yes i am fully aware of the fact the chip would degrade faster (maybe knock a good few months of its life) but i am already looking forwards to iver bridge to replace this current setup so i have been wondering why not enjoy the chip as much as possible!!

Temps at 5ghz/1.51 were 37/38 idle 54-56 after 3 mins prime after 30 mins 62-4 ish, I did however crank my fans up ( although when my fans are on low i get @ 4.4ghz 27 idle ish and 44 max load, i really do love my push pull Megahalems with diamond paste)

Just looking for some input before i go and do somthing silly ! :rolleyes:

i would stick to intel's 1.38V to be honest. the last thing you want is the processor to break before ivybridge

Were does Intel say that.

Didn't Ocuk and Intel both do some testing hence why OCUK add this to every Sandy they sell..

***OVERCLOCKING GUIDELINES***

- Do not exceed 1.35-1.38v core voltage, doing so could limit lifespan of the CPU
- Do not overclock with BCLK, again doing so could limit lifespan of the CPU
- Recommended memory voltage is 1.50v, so make sure to run your memory at 1.50v, higher could limit lifespan of the CPU
- These recommendations come from OcUK and Intel, your warranty is un-affected but we highly recommend you adhere to the above to make sure your CPU lifespan is un-affected
- All Sandybridge CPU's worldwide should be run at the above or lower voltages, no higher!

Not a set in stone thing, just a recommendation, most 24/7 clocks iv seen people are keeping under 1.4v.

+1 that is safer

1.5 volts for 24/7 usage is chip suicide as far as anyone can tell at the moment. Keep it under 1.4 to be safe.

I wouldn't go for 5GHz as it is straining your system too hard and will limit the lifespan of your CPU as a result.

it isnt the frequency that strains the system, it is the voltage, if i could get to 5GHZ under 1.4V then it would be excellent - but this is almost impossible

Ocuk did say that keeping under 1.35 was perfectly fine but you should not really go over that. Intel state on there website that the 2600k max volts is 1.52, so i was just wondering if to push it that far for a few months or not...

bifday2k · 19 Jun 2011 at 12:02

Wasn't just OCUK saying it, they where testing along side intel at the time, in other words calls back and forth whilst testing and what not, as at launch quite a few cpu's where being returned due to getting to much volts put through them, so thats why both tested and came up with that max safe voltage for 24/7 use. Intel really should change that on there site, but hey ho lol.

That being said, as long as your cooling can keep the thing cool, u can pump what u personally like into it, just you run the risk of frying it the higher you go.

Plenty of extreme overclocking guys pump 1.8/1.9v into them under sub zero cooling and the cpu sometimes survives, but these guys don't mind killing cpu's/mobo's.

Best way to think about it, is it worth the risk frying a £250 cpu, just for 400mhz more speed for a few months, not saying it will happen, but there is always a chance when u go to high on vcore.

That vcore for short bursts of benching would be fine, just 24/7 i personally would'nt. But its always user choice, we can only advise of the risks.

Do you even need any boost to your clockspeed anyway?

joxang · 19 Jun 2011 at 13:09

Definitely keep it around 1.4V for 24/7. Some people are running at a shade under 1.45V 24/7 and say it's OK, but I also know someone who tried running at 1.45V and couldn't keep it stable after about 2 weeks, so some of these chips do seem to degrade at high voltages.

So far I haven't read about anyone having problems at 1.425V 24/7 but it hasn't been that long either.

Sampsy has a point. It's unlikely that for most applications you'll use the extra power, and since you're almost certainly damaging your CPU at 1.51V it isn't worth it. If I were you I'd get 4.5 stable and settle there, 4.6 if you really think it makes a difference.

koooowweeee · 19 Jun 2011 at 14:29

There is no set in stone safe volts for these chip but most people say 1.45 but Intel have said that some sandy chips have a VID of 1.52v

as each chip is different OCUK Can't really say a safe volts. Its just a guess really. If it came from Intel then i would say yes that's the safe volts but no one knows.
